Does the Pro 3EM support 3phase (3x 400V +N)

[Rafa]

Hello,

 

I'm looking to install a Shelly Pro 3EM (120A) to monitor my whole house energy consumption. 

My (Belgian) connection is a 3phase 3x 400V +1N, does the Pro 3EM support this type of connection?

@Rafa that would be the Pro 3EM 400A version that would be an option here

Why should he use the 400A version, @Heinz? A Shelly pro 3EM would do the job…

With 400V would that not be above the 120A range ?

Voltage is voltage, ampere (A) is current.

400V is both supported by Shelly pro 3EM and pro 3EM-400. The 400 is Ampere. Thus, the Shelly pro 3EM-400 has larger current clamps.

I suppose @Rafa is asking cause in wide parts of Belgium a Y network without neutral is used with 230/133V. Mains socket are connected between two live wires to achieve 230V. The voltage between live and ground (133V) is IMHO not used. For safety, a PE wire is led to each premise.
